Difference between negotiated, derived and fee schedule negotiated type

[hung-payerprice]

I'm confused about the difference between the 3 negotiated types negotiated, derived and fee schedule If I understand correctly, the units of all 3 rates are dollar, not percentage.

Can someone please explain to me how they are different? An example would be great e.g if there are 3 different rates, one for each type, when to use each of them? Thanks!

The previous discussion here didn't seem to reach a conclusion.

The official doc said the following but i don't really understand what they mean

negotiated: If applicable, the negotiated rate, reflected as a dollar amount, for each covered item or service under the plan or coverage that the plan or issuer has contractually agreed to pay an in-network provider, except for prescription drugs that are subject to a fee-for-service reimbursement arrangement, which must be reported in the prescription drug machine-readable file. If the negotiated rate is subject to change based upon participant, beneficiary, or enrollee-specific characteristics, these dollar amounts should be reflected as the base negotiated rate applicable to the item or service prior to adjustments for participant, beneficiary, or enrollee-specific characteristics.

derived: If applicable, the price that a plan or issuer assigns to an item or service for the purpose of internal accounting, reconciliation with providers or submitting data in accordance with the requirements of 45 CFR 153.710(c).

fee schedule: If applicable, the rate for a covered item or service from a particular in-network provider, or providers that a group health plan or health insurance issuer uses to determine a participant’s, beneficiary’s, or enrollee’s cost-sharing liability for the item or service, when that rate is different from the negotiated rate.
